2 Claims.

This invention relates to coin control mechanism in dispensing machines and particularly to the tripping and switching mechanism thereof.

The object of the invention is to provide for such machines positive means whereby the insertion of a coin will close an electric switch and permit a receptacle in a carrier to be filled or the carrier to be charged. When the receptacle is filled or the carrier charged, its increased weight displaces the carrier, discharges the coin and immediately and positively opens the switch. The removal of the filled receptacle or the charge from the carrier permits the replacement of the carrier in its normal position to receive an empty receptacle and a fresh charge.

Reference is made to the accompanying drawing in which:-

Figure 1 shows a side view.

Figure 2 shows a front view in part.

A coin chute '7 mounted on the frame has its lower end normally closed by one end 41 of a lever 4 journalled in a U-shaped bracket 3 from above. The lever 4 is normally slightly inclined upwardly toward the coin chute 7. Mounted in a clip 43 on the lever 4 above the journal 30 and parallel to the lever is a mercury switch 5 which owing to the incline is normally open. Looped wires 52 lead from the switch 5 to a binding post 31. When a coin 8 is dropped in the chute '7 on striking the lever 4" it lowers the end 41 struck by the coin and thereby converts the incline to a decline. The mercury thereupon runs to the contact end 51 of the switch 5 and the switch is closed. The coin 8 is held with its upper edge still in the chute '7. The switch 5 being closed the operation of filling a receptacle takes place. The receptacle is supported in a carrier 2 pivotally mounted at 20 and normally held in a raised position by a counter weight 22 on the arm 21.

A bracket 23 projecting from the wall of the carrier 2 extends under the lever 4 which it supports in its closed switch position during the filling of the receptacle. When the receptacle in the carrier 2 has become filled or the carrier 2 receives its charge, its weight overcomes the counter weight 22 and the carrier 2 tilts forward and downwards. The bracket 23 descends with the carrier 2 and permits the lever 4 to decline further, thereby releasing the coin 8 which falls and is carried by a slide to a coin box. A bell crank lever 6 is pivoted to the frame 1 below the lever 4, its upper arm projecting under the lever 4 and forward of its journal 30. The lower arm 61 extends across and under the projecting edge 24 of the bracket 23.

When the carrier 2 has descended nearly to the limit of its downward movement the projecting edge 24 of the bracket 23 lowers the lower arm 61 of the bell crank lever 6, its upper arm 60 pushes the lever 4 upwards above the level and the mercury 50 leaves the contact end 51 of the switch 5, which is opened, and runs to the free 65 end, thereby tilting the lever 4 back to its normal position.

By this means as soon as the receptacle is filled or the carrier 2 receives its charge, the switch 5 is positively opened and overflowing and waste prevented.

By means of a movable counter weight 50 on the lever 4 a more positive tilting is obtained in either direction than where a fixed counterweight and the coin affect the tilting, and the necessity of a delicately balanced leven with its uncertain action is avoided. A ball run and balls could be used in place of a large mercury switch with a greater quantity of mercury in it than is usual.

By this method of tripping and switching a coin operated machine, certainty of action is obtained, construction is simplified and adjustment is made permanent.

I claim:

1. In a machine of the type specified a tiltable carrier adapted to receive a charge, electrically operated means for feeding the charge to the carrier, an electric circuit, a mercury switch therein, a lever on which the switch is 90 centrally mounted, a coin chute mounted to feed a coin to the end of the lever, and thereby tilt it to close the switch, a bracket extending from the carrier adapted to limit the tilting of the lever and retain the coin thereon, a pivoted bell crank lever operated by the bracket when the carrier has received its charge and tilts forward and an arm to the bell crank lever extending under the switch lever adapted to tilt the switch to an open position.

2. In a machine of the type specified, a. tiltable carrier adapted to receive a charge, an electric circuit operating means for feeding the charge to the carrier, a mercury switch therein, a tilting lever on which the switch is centrally 10 mounted, a coin chute mounted to feed a coin to one end of the lever and thereby tilt the switch to a closed position, a bracket extending from the carrier and under the lever normally limiting the tilting to retain the coin no thereon and means operated by the bracket to open the switch when the carrier is charged.
